The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' that you can use without any external files.
|
|
The files in this folder are only provided as a convenience, you can use any of your own .TTF files.
|
|
|
|
Fonts are rasterized in a single texture at the time of calling either of io.Fonts.GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().
|
|
|
|
If you want to use icons in ImGui, a good idea is to merge an icon font within your main font, and refer to icons directly in your strings.
|
|
You can use headers files with definitions for popular icon fonts codepoints, by Juliette Foucaut, at https://github.com/juliettef/IconFontCppHeaders

LOADING INSTRUCTIONS
|
|
---------------------------------
|
|
|
|
Load default font with:
|
|
|
|
ImGuiIO& io = ImGui::GetIO();
|
|
io.Fonts->AddFontDefault();
|
|
|
|
Load .TTF file with:
|
|
|
|
ImGuiIO& io = ImGui::GetIO();
|
|
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
|
|
|
|
Detailed options:
|
|
|
|
ImFontConfig config;
|
|
config.OversampleH = 3;
|
|
config.OversampleV = 1;
|
|
config.GlyphExtraSpacing.x = 1.0f;
|
|
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
|
|
|
|
If you have very large number of glyphs or multiple fonts:
|
|
|
|
- Mind the fact that some graphics drivers have texture size limitation.
|
|
- Set io.Fonts.TexDesiredWidth to specify a texture width to minimize texture height (see comment in ImFontAtlas::Build function).
|
|
- You may reduce oversampling, e.g. config.OversampleH = 2 or 1.
|
|
- Reduce glyphs ranges, consider calculating them based on your source data if this is possible.
|
|
|
|
Combine two fonts into one:
|
|
|
|
// Load a first font
|
|
io.Fonts->AddFontDefault();
|
|
|
|
// Add character ranges and merge into the previous font
|
|
// The ranges array is not copied by the AddFont* functions and is used lazily
|
|
// so ensure it is available for duration of font usage
|
|
static const ImWchar icons_ranges[] = { 0xf000, 0xf3ff, 0 }; // will not be copied by AddFont* so keep in scope.
|
|
ImFontConfig config;
|
|
config.MergeMode = true;
|
|
io.Fonts->AddFontFromFileTTF("DroidSans.ttf", 18.0f, &config, io.Fonts->GetGlyphRangesJapanese());
|
|
io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 18.0f, &config, icons_ranges);
|
|
|
|
Add a fourth parameter to bake specific font ranges only:
|
|
|
|
// Basic Latin, Extended Latin
|
|
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesDefault());
|
|
|
|
// Include full set of about 21000 CJK Unified Ideographs
|
|
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
|
|
|
|
// Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
|
|
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesChinese());
|
|
|
|
Offset font vertically by altering the io.Font->DisplayOffset value:
|
|
|
|
ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
|
|
font->DisplayOffset.y += 1; // Render 1 pixel down
|
|
|
|
|
|

|
|
REMAP CODEPOINTS
|
|
---------------------------------
|
|
|
|
All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese CP-1251 for Cyrillic) will not work.
|
|
In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
|
|
You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code.
|
|
|
|
|
|
---------------------------------
|
|
EMBED A FONT IN SOURCE CODE
|
|
---------------------------------
|
|
|
|
Compile and use 'binary_to_compressed_c.cpp' to create a compressed C style array. Then load the font with:
|
|
|
|
ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
|
|
|
|
Or
|
|
|
|
ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);
